a bottom rail provided at the other end of the shielding material and having a longitudinal notch at its longitudinal end;
a frame fixed to the opening and having a shielding piece that closes a gap between the opening and the shielding material;
and
part of the shielding piece overlaps the shielding material in the longitudinal direction of the support member and is inserted through the notch;
A projection that allows point contact or line contact between the shielding piece and the inner wall surface on at least one surface of the shielding piece or on at least one surface of the front and rear inner wall surfaces of the bottom rail forming the notch. Blinds are formed. A blind according to claim 1,
The convex portion is a shield piece-side convex portion provided on at least the front surface of the front and rear surfaces of the shield piece. A blind according to claim 2,

The bottom rail has two inner wall-surface-side protrusions on both surfaces of the front and rear inner wall surfaces forming the notch portion, the blinds having two inner-wall-surface-side protrusions facing each other outward in the longitudinal direction from the positions of the shielding-one-side protrusions. A blind according to claim 4,
The frame has the shielding piece-side projections at corresponding positions on both front and rear surfaces of the shielding piece.
